The spindle motor is integrated with the disc by incorporating one of the poles or coils of the motor with a region on the disc, and the remaining portion of the motor being distributed over an internal surface or surfaces of the housing for the disc, or over the edge of an adjacent disc. By activating the portion of the motor which is supported from the disc housing, the disc can be rotationally driven. The motor poles may be either deposited or etched on the disc, or separately formed and attached to the disc housing. The result is a substantially smaller height disc drive, achieved with a much reduced cost.
